Previously, we reported on the upcoming CAMM2 modules from MSI. Now, MSI has conducted a comparative test between the new CAMM2 memory modules and traditional DDR5 to address concerns about their performance and efficiency. CAMM2 memory, touted as a more compact alternative to SO-DIMM, is still not widely adopted in the market.
For the test, memory modules of both types with identical specifications were used: DDR5-7200 and timings of CL38-44-44-105 (2T). The results from AIDA64 showed the following performance (CAMM2 vs SO-DIMM):
- Read Speed: 105.83 GB/s vs 106.76 GB/s
- Write Speed: 88,637 MB/s vs 91,821 MB/s
- Copy Speed: 94,772 MB/s vs 94,619 MB/s
- Latency: 66.3 ns vs 65.3 ns
While traditional DDR5 SO-DIMM modules slightly outperformed CAMM2 in read and write speeds, the difference was only about 3%, and CAMM2 even showed better results in copy speed. In essence, CAMM2 modules are nearly on par with classic memory, offering significantly more compact dimensions—up to 57% smaller compared to SO-DIMM in dual-channel mode. Currently, the fastest CAMM2 modules support DDR5-9600.
